The British constitution is about to do the thing it does best and explain least. A prime minister who won a landslide twenty-three months ago is preparing to leave office, and not one voter will be asked to ratify his replacement. Labour’s 2024 majority was never Keir Starmer’s personal property. It belongs to the party, and the party can hand it to whomever it likes. This is not a loophole. It is the system working as designed, and it is the reason the Conservatives are spectators to a drama that decides who governs them.
